Brand: Optimum Balance Products (OBP)
This steel brake adapter has a male 7/16-20 inverted flare (concave) fitting on one end and a 4AN male (7/16-20, 37° convex) on the other. The overall length is 1.38". Sold individually.
Both the SAE end and the 4AN end are slightly longer than on our Standard 4AN to 7/16-20 Inverted Flare Adapter (Part No. 3265-11). The extra length helps to reach into deeper ports to seal without resorting to a crush washer.
We also offer a Long 4AN to 7/16-20 Inverted Flare Adapter (Part No. 3265-10), which has an extra 1.1" shank between the hex and the 4AN end for extra clearance in tight installations.
